When the Giants called New York home, the team played at the Polo Grounds in upper Manhattan. The stadium sat literally miles away from Yankee Stadium and was unique for its incredibly short corners and very deep center field. The Polo Grounds is a classic stadium in MLB The Show 25, playable in both Diamond Dynasty and other modes. But for Diamond Dynasty, it’ll need to be unlocked first.
Where to find Polo Grounds in Diamond Dynasty
To get the Polo Grounds in MLB The Show 25 Diamond Dynasty, one will need to get 15 triples in any single-player or online game mode (excluding Moments & Showdowns).

This is a part of the new ‘My Legacy’ Programs within Diamond Dynasty. My Legacy is designed to reward players who accumulate a lot of hits, doubles, home runs, PXP, wins, and more stats. Most of the rewards found within these programs are either Icons or customization options, like Bats or Socks.
The Polo Grounds, though, is an exception.
This is a change, compared to past MLB The Show games. Traditionally, the Polo Grounds has been the reward for collecting all the Diamond Stadiums, which consist of classic parks like Shea Stadium, old Yankee Stadium, and Turner Field, among others.
For ’25, the Kingdome in Seattle is now the reward for that collection.
Easiest way to unlock Polo Grounds
Our advice is to just do it in single-player action. Load up on a team filled with fast players who have decent power (i.e. Corbin Carroll, Julio Rodriguez, etc.) to get balls into the gap.
Then, try to find a stadium where it’s somewhat cavernous. Comerica Park and Coors Field are good options. Yes, one might think it’s counter-intuitive to pick Coors because of the high elevation. But, if you can get the ball into the left-center field gap, there’s a good shot at a triple.
